[0002] Self-adhesive high-temperature resistant PET film is a functional film made from PET base film through a special process to give it self-adhesive properties and the ability to withstand high temperatures. It possesses the excellent properties of PET film, such as good mechanical properties, chemical stability, and dimensional stability, and its self-adhesiveness and high-temperature resistance expand its application range.
[0003] During PET film slitting, the PET film is continuously slitted by die-cutting. The desired PET film shape will fall off after slitting. However, the die-cutting plate is not precise enough, which will cause the PET film to be cut inaccurately during die-cutting. As a result, the slitting product will remain on the film. The remaining product needs to be removed again. Therefore, there is a need to provide a way to collect the remaining product film during the slitting process, reduce manual processes, and improve production efficiency. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0028] Please see Figure 1-4 As shown, this utility model is a continuous slitting device for self-adhesive high-temperature resistant PET film, comprising:
[0029] The system includes an operating table 11, a lower mold 12, an upper mold 13, a fixing frame 14, and a hydraulic cylinder 15. The lower mold 12 is fixed to the middle of the upper surface of the operating table 11, the upper mold 13 is located above the lower mold 12, the fixing frame 14 is fixed to the rear side of the operating table 11, the hydraulic cylinder 15 is fixed to the lower surface of the fixing frame 14, and the output end of the hydraulic cylinder 15 is fixed to the upper surface of the upper mold 13. A film roll 16 passes through one side of the operating table 11, and a storage roll 17 passes through the other side of the operating table 11. A motor 18 is fixed to the rear side of the storage roll 17, and a rotating shaft is fixed to the output end of the motor 18. The rotating shaft passes through the storage roll 17.
[0030] The operating table 11 serves as the installation base for the entire device. The lower mold 12 works in conjunction with the upper mold 13 and is a key component for forming the die-cut shape. The hydraulic cylinder 15 provides power for the up-and-down movement of the upper mold 13. The pressure generated by the hydraulic system pushes the upper mold 13 downward to realize the die-cutting action on the PET film.
[0031] The blanking assembly includes a connecting plate 21, a movable groove 22, a slider 23, a threaded hole 24, and a threaded rod 25. The connecting plate 21 is fixed to one side of the upper mold 13. The movable groove 22 is opened in the middle of the connecting plate 21. The slider 23 slides through the movable groove 22. The threaded hole 24 is opened in the middle of the slider 23. The threaded rod 25 is threaded through the threaded hole 24.
[0032] When the upper mold 13 moves downward, the connecting plate 21 also moves downward, thereby driving the slider 23 and the threaded rod 25 to perform corresponding actions, realizing the synchronization of the movement of the upper mold 13 and the feeding action. The movable groove 22 provides a guiding function for the sliding of the slider 23, allowing the slider 23 to slide in the movable groove 22 along a predetermined direction. The change in the position of the slider 23 will affect the relative positional relationship between the threaded rod 25 and the PET film. The slider 23 and the threaded rod 25 are connected together by a threaded connection through the threaded hole 24, so that the rotational movement of the threaded rod 25 can be converted into the linear movement of the slider 23.
[0033] The lower mold 12 is fixed with two fixing plates 26 on both sides. A first placement roller 27 slides through one side of the two fixing plates 26, and a second placement roller 28 slides through the other side of the two fixing plates 26. A connecting post 29 is installed on one side of the fixing plate 26, and two rubber rings 291 pass through the outer surface of the connecting post 29. PET film is placed on the surface of the first placement roller 27 and the second placement roller 28, and the outer surface of the rubber rings 291 is in contact with the PET film. The lower end of the threaded rod 25 is aligned with the middle of the first placement roller 27 and the second placement roller 28.
[0034] The fixed plate 26 provides stable support and guidance for the first placement roller 27 and the second placement roller 28. The first placement roller 27 and the second placement roller 28 prevent the PET film from becoming loose or wrinkled, thus ensuring the die-cutting quality. The rubber ring 291 is made of rubber with a large coefficient of friction, which can effectively increase the friction between the rubber ring and the PET film, so that the PET film generates a certain tension at the connecting post 29, thereby ensuring the tension stability of the PET film throughout the entire conveying process.
[0035] Working principle:
[0036] When slitting PET film, the film roll 16 is placed on one side of the operating table 11, and then the film is passed through the middle of the lower mold 12 and the upper mold 13. The film is then passed through the rubber ring 291 and placed on the surface of the first placement roller 27 and the second placement roller 28. Finally, the film is wound around the outer surface of the storage roll 17. Then, the motor 18 and the hydraulic cylinder 15 are started. The motor 18 drives the storage roll 17 to rotate, so that the film moves between the upper mold 13 and the lower mold 12. At the same time, the upper mold 13 slits the required product film. When the hydraulic cylinder 15 drives the upper mold 13 to cut downward, it simultaneously drives the connecting plate 21 to press downward and pushes the slider 23 so that the slider 23 is aligned with the cutting groove of the PET film. Then, the threaded rod 25 is rotated. At this time, the lower end of the threaded rod 25 is also aligned with the PET film. The threaded rod 25 can press down on the cutting groove each time it is cut, so that the product film remaining in the cutting groove falls off.
[0037] In this step, the connecting plate 21 drives the slider 23 and the threaded rod 25 to process the cutting groove. All actions work together in the whole process to realize the integrated operation of continuous cutting and automatic cleaning. No manual cleaning is required, which greatly improves production efficiency.
[0038] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0039] The collection component includes a collection frame 31, a mounting slot 32, and an access hole 33. The collection frame 31 is placed inside one side of the operating table 11, the mounting slot 32 is opened on both sides of one side of the operating table 11, and the access hole 33 completely penetrates the two mounting slots 32.
[0040] The collection frame 31 is used to collect products that fall from the PET film cutting groove during the slitting process. The mounting groove 32 provides the mounting position and movement space for components such as the movable column 34 and the baffle 35. The movable hole 33 provides a sliding passage for the movable column 34.
[0041] The movable column 34 slides through the movable hole 33, and a baffle 35 is fixed on the outer surface of the movable column 34. The baffle 35 is located in the mounting groove 32. A spring 36 is fixed on one side of the baffle 35. The movable hole 33 extends out of the end of the movable column 34, and the end of the movable column 34 intersects with the collection frame 31.
[0042] When the staff applies external force to the end of the movable column 34, the force can be transmitted to components such as the baffle 35 and the spring 36 through the sliding of the movable column 34, thereby realizing the loading and unloading control of the collection frame 31.
[0043] Working principle:
[0044] During the slitting process, the cutting grooves on the PET film are cleaned simultaneously, allowing the products to fall directly into the collection frame 31. When the collection frame 31 is full, the operator simply pushes the movable column 34 to both sides, causing the baffle 35 to move to both sides simultaneously. This compresses the spring 36 into the mounting groove 32, and the end of the movable column 34 is offset from the collection frame 31, allowing the collection frame 31 to be removed from the operating table 11. Then, an empty collection frame 31 is replaced. Under the elastic force of the spring 36, the spring 36 quickly returns to its original shape, driving the movable column 34 to move towards the center and install the collection frame 31 into the operating table 11. The slitting process cleans the cutting grooves on the PET film simultaneously, allowing the products to fall directly into the collection frame 31 without the need for additional machine shutdown for cleaning, ensuring the continuity of the slitting work and greatly improving production efficiency.
[0045] This step involves a simple and easy-to-use design for replacing the collection box 31. Workers can easily remove the full collection box 31 and replace it with a new one without having to carry it out laboriously or perform complicated disassembly and installation, thus reducing the difficulty and labor intensity of the workers.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
